MACHINE FOR SCALDlNG AND STICKING FUR-BATS T0 FELT HAT-BODIES.

SPECIFICATION forming part'of Letters Patent No. 254,349, dated February 28, 1882.

' Application filed January 6, 18152. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. MALLouY, of Danbury, in the county of Fairfield and State ofOonnecticut, have invented certain new and useful Improvements relating toMachines for Scalding and Sticking Fur-Batsto Felt Hat-Bodies, of which the following is a specification.

The object of the invention is to facilitate the introduction and removal of the hat-bodies, and to graduate the force with which; the hat-bodies are compressed in the machine.

I employ rollers working in such relation to each other that the hat-body, with the fur-bat previously applied thereto and slightly adhering, shall, by the action of the rollers, beturned and manipulated in the presence of heatand moisture, so as to insure the engagement of the several fibers of the fur strongly and properly with the firmer felted body of the hat.

My invention provides means whereby the roll-1 ers are conveniently moved together and apart and adjusted in various positions, while they are at the same time continuously turned with the proper velocity.

The accompanying drawings form a part of this specification, and represent what I consider the best means of carrying out the invention.

Figure 1 is a plan view of the machine. 2 is a side elevation of the same, a portion being broken away to better show the parts beyond. Fig. 3 is an end elevation with a part broken away. Fig. 4 is an elevation of the opposite end, the right hand in Fig. 2; and Fig. 5 is a vertical transverse section through the main body, showing the rollers at work treating one or more hats.

Similar letters of reference indicate like parts in all the figures.

A is a case or tank of wood or other suitable material, to be kept partially filled with water at a nearly or quite boiling temperature, the heat being maintained by steam circulated through pipes a, and allowed to escape into the water through small orifices, as will be readily understood. 7

B, G, andDareribbed rollers, of wood or other I suitable material, revolved all in the same direction and arranged so that the hat-body in,

Fig.

having the for bat properly applied and b. ing properly rolled up in a separate fabric, may be h eldfand revolved in the open-topped space included between the bodies of the rollers. One of the rollers is mounted in movable bearings, with provision for adjustment at greater or less distances from the others, as required for, difierent sizes of the masses or difi'erent characters of the material to'be treated. The power is applied through a belt, G, from any suitable motor. This belt runs on a pulley,-

H, keyed on a short shaft, h, which does not extend across'the tank A, but simply turns in bearin gs outside thereof at the end. It carries agear-wheel, H, which engages with another gear-wheel,1,turniuglooselyonastud,i. This gear-wheel I engages with the gear-wheel B on the shaft of the roller B, and also engages with the gear-wheel C on the shaft of the roller 0, and consequently turns these rollers by the direct force thus imparted. These rollers O and B may be held-in fixed bearings. It is important that the lower be thus held, as otherwise elaborateprovisions would be necessary toprevent an escape of water atthe bearings. The rollerD is worked at so high a level that its bearings are 'always above the water, and no stuffing-boxes or other means of arresting water, are required therefor. The bearings of sufiicient length applies on both the pulleys 13* and D*, and also traverses down under the idle-pulleys K and L, turning on studs mounted at a considerable distance below, all as represented. The stud k on which one of these pulleysKturns is adjustable by ordinary means as a collar and nut in a slot, a, formed in the fixed framing A.

P P are stop-cocks arranged at different levels, by opening one of which at intervals, or leaving it constantly open, the surplus water received by the condensing of the steam from the pipe at, or by any other means, may be discharged, and the surface of the water in the tank A kept at the proper level.

In operation the several rollers B, G, and D are turned uniformly, and cause, by virtue of their ribbed surfaces and close relations, the required action on the mass m to iriduce the perfect union of the root of each fiber of fur with the outer surface and even with middle of the thickness of the hat-body to which it is applied; but in order to attain this end it is important thatthe width of the space within the series of rollers be increased and diminished at times. This my invention allowsby' simply slacking the nuts F and changing the positions of the levers E, and consequently of the roller D, and then again setting the nuts F tightly and holding all firmly until a further change is required.

I can shift the position of the roller D to extricate the mass m without injury in case of any accident. I can shift the position of said roller by the means shown, or by an easy addition, each time the material is to be removed or introduced; but with the rollers arranged as shown'this is not necessary.

The lower roller, 0, is partly immersed in the hot water and continually supplies heat and moisture to the mass m being treated. The turning of all the rolls and of the mass m subjects the latter at all points to indefinite gentle compressions and partial release from compression. If it be desired that the action be more compressive, the roller D must be set nearer the roller B. If a contrary effect is desired, the roller 1). must be shifted away from the roller 13.

Modifications may be made in many of the details without departing from the principle or sacrificing the advantages of the invention. I can apply the power by other means to the train of rollers B O. I propose in some cases to extend the shaft of the roller B and apply the belt G to a pulley and loose pulley thereon, retaining the central idle-wheel, I, to convey the motion therefrom to the lower roll, 0. In all cases I propose to communicate the motion to the movable pulley D by the belt G through the aid of the pulleys K and L. The levers E E may be extended down farther, or not as far, the pivots e 6 being always in the proper line, so that the turning of the levers E E will not materially tighten or slaken the belt Gr- In theory the best position for the pivots e e is in a line midway between the axes of the idle-pulleys K and L; but I do not consider it expedientin most cases to extend the levers E so far down, as the change in tightness of the belt G, when the centers are higher, is too small to be of importance.

- I do not claim anything set forth in the patent to Ezra A. Mallory, July 12, 1881, No. 244,271, nor in the several patents to J. T. Waring, George Yule, and P. V. W. Bishop. My invention difiers substantially from all of those. It allows the easy introduction and extraction of the hat-body without changing the position of the rollers for the purpose, while allowing a ready and delicate adjustment of the rolls for different sizes or characters of the hat-bodies.

I claim as my invention.

1. The rollers B G D, arranged to leave a constant space in which the hat-body can be introduced and removed, in combination with the levers E, adjusting means F therefor, pulleys 13* D*, belt G, and pulleys K L, arranged for joint operation, as herein specified.

2. The rollers B G D, arranged to provide a space at the top in which the hat-body can be introduced and removed, gears B G, pulleys B* D*, levers E, belt G, and pulleys K I}, in combination with each other and with the water-tank A and steam-pipes a, as herein specified.

In testimony whereof I have hereunto set my hand, at Danbnry, Connecticut, this 24th day of December, 1881, in the presence of two subscribing witnesses.
